P21 activated kinase 2 promotes pancreatic cancer growth and metastasis.

Pancreatic cancer has an overall 5-year survival rate of only 9%, due to its rapid metastasis and poor prognosis. To combat this disease, novel therapeutic targets and biomarkers are required. In this study, immunohistochemistry was used to detect the expression of P21 activated kinase 2 (PAK2) protein in the tissues of cancer and the paired adjacent normal tissues.

Short-term clinical effects of photodynamic therapy with topical 5-aminolevulinic acid for facial acne conglobata: an open, prospective, parallel-arm trial.

Background: Acne conglobata is hardly curable and easily leads to scar formation after treatment using traditional methods.

Aim: To develop a novel way to treat acne conglobata.

Methods: Seventy-five patients with facial acne conglobata were included in this clinical study and divided into either a treatment group (n = 35) to receive photodynamic therapy (PDT) with topical 5% 5-aminolevulinic acid and red light once every 10 days for a month or a control group (n = 40) to receive a Chinese herbal medicine mask plus red light once per week for the same duration.
